ALL BALLS RACING — 47-2037 Fuel Pump Rebuild Kit, Plug-and-Play Premium Component Assembly, Economical Performance Restoration for Polaris RZR 170 UTV and Yamaha EFI Off-Road Dirt Bike & Sport ATV Models

Restore hard-hitting throttle response, proper fuel system pressure, and maximum engine performance with the ALL BALLS 47-2037 Fuel Pump Rebuild Kit. Over time, heavy trail use, sediment contamination, and degraded ethanol-blended fuels break down your factory fuel delivery system, causing hard starting, severe engine bogging, or complete fuel pump failure. Instead of spending hundreds of dollars on an entirely new factory assembly, this complete drop-in overhaul kit provides an economical, industrial-grade solution to completely rebuild your existing OEM fuel pump module.

Manufactured to match strict OEM specifications, this comprehensive kit features a premium-grade black and white mechanical configuration that comes ready for a fast, hassle-free installation. Every package includes the core high-efficiency pump unit, precision-woven fuel filter strainer, specialized flexible fuel hoses, heavy-duty mounting clamps, and direct plug-and-play wiring harnesses tailored specifically to your vehicle's requirements. Whether you are maintaining a youth Polaris RZR 170 utility machine, feeding a high-RPM Yamaha YFZ450R sport quad, or servicing a modern fuel-injected YZ250F, YZ450F, or WR series off-road bike, this kit delivers consistent fuel flow to eliminate lean-running conditions across all terrains.

Moto-House MX Pro Tip:

A failing fuel pump can completely ruin a race weekend or trail ride, often mimicking electrical issues or clean carburetor issues even on fuel-injected machines. When your pump struggles to maintain correct system PSI, your engine runs lean, which skyrockets combustion temperatures. Installation Tip: Before cracking open your fuel tank to pull the pump module, wash down the entire vehicle to prevent dirt, dust, and sand from tumbling into the open gas tank. Take your time when extracting the old plastic module assembly. When mounting the new fuel filter strainer and internal hoses, verify that all ear-clamps are squeezed perfectly tight to prevent internal pressure drops. Maintenance Advice: Lubricate the main tank-to-pump sealing O-ring with a tiny smear of clean grease or fuel before final assembly to guarantee an airtight, leak-free seal. Always check that the internal tank is clear of any resting rust or sediment before inserting your freshly rebuilt unit.
